CoCounsel Legal previews ChatGPT Enterprise access
Thomson Reuters is previewing a CoCounsel Legal experience that brings specialized research, analysis, and drafting into ChatGPT Enterprise while keeping the systems distinct. Its outputs remain grounded in Westlaw, Practical Law, and organizational knowledge for verifiable legal work. ([announcement](https://www.thomsonreuters.com/en-us/posts/innovation/thomson-reuters-and-openai-advancing-an-open-ecosystem-for-legal-ai/), [product page](https://legal.thomsonreuters.com/en/products/cocounsel-legal))
The strategic move is less about another legal chatbot and more about making specialist legal intelligence available wherever professionals already work.
- –ChatGPT Enterprise becomes the conversational front door, while CoCounsel retains its proprietary legal research and drafting capabilities.
- –Grounding responses in Westlaw, Practical Law, and firm knowledge offers stronger provenance than general-purpose chatbot output.
- –The biggest implementation challenge will be permissioning: authorized matter context, confidentiality boundaries, and auditability must survive the handoff between systems.
- –This positions Thomson Reuters against an expanding field of enterprise legal AI platforms, including offerings from OpenAI, Anthropic, Google, Harvey, and Legora.
